Description

A user reported that if a veracrypt volume is encrypted with a passphrase longer than 64 characters, it is not possible to open it in Tails. Given it is possible to create such volumes outside of Tails, If it is not fixable, the documentation should at least mention that problem.

History

#1 Updated by segfault 2020-02-12 17:41:50

  • Status changed from New to Confirmed

Reproduced and reported upstream: https://gitlab.com/cryptsetup/cryptsetup/issues/532

  • Status changed from Confirmed to In Progress
  • Assignee deleted (segfault)
  • Target version set to Tails_5.0
  • Type of work changed from Research to Wait

The issue has now been fixed upstream in commit f18cd7ae813cb6732362956565cd1584aa4fe4e9, which should be included in the next cryptsetup release. The most recent version is 2.3.0, so once we get a cryptsetup > 2.3.0 via Debian repos, this will be fixed in Tails (I guess that will be Tails 5.0 based on Bullseye).

#3 Updated by intrigeri 2020-03-25 08:38:58

… and the cryptsetup 2.3.1 Release Notes read:

> * Support VeraCrypt 128 bytes passwords.
> VeraCrypt now allows passwords of maximal length 128 bytes
> (compared to legacy TrueCrypt where it was limited by 64 bytes).

Documenting is not fixing. Let’s keep this ticket open until it’s actually fixed in 5.0.
